There are more associations for genetics than previously thought. Using pooled DNA sequencing researchers found that about 1/3rd of ALS is genetically linked.
There are blood brain barrier problems with ALS and so they are looking at that:
Inhibiting the blood-brain and spinal cord barrier's drug efflux transporters improves the efficacy of ALS treatment with riluzole in a mouse model.So how can diet improve this?
ACE Inhibitors may help
The use of angiotensin-converting enzyme inhibitors (ACEIs) was associated with a significant reduction in the risk of developing amyotrophic lateral sclerosis (ALS) in a new case-control study conducted in TaiwanCould "Leaky Gut" be increasing microbes and cause a whole range of these diseases? Better take probiotics. Leaky gut diet should also help, http://thepaleodiet.com/paleo-foods-heal-leaky-gut/
This is about a mechanism for a malfunctioning protein which is believed to be responsible for ALS.
